[. . . ] 3. 2 PHANTOM POWERED MICROPHONES Phantom powered microphones such as condenser and some ribbon microphones require external power to preamplify the microphone acoustic pickup. These microphones typically have much higher output than dynamic microphones. Hence the -20dB pad is almost always necessary when close micing to avoid clipping the amplifier. 3. 3 LINE LEVEL INPUTS The 1/4" inputs on the DigiMAX LT are designed for use with line level or low impedance inputs not instrument level inputs. These inputs will work for line level devices such as keyboards, samplers, drum machines, CD players, etc. 3. 4 APPLICATION GUIDE Outboard Dynamics Processing Example The DigiMAX LT has an insert on every channel that allows you to insert your own dynamics processor, such as a compressor, EQ, limiter, or etc. To do this, all you need is your dynamics processor and a TRS insert cable. This cable is Yshaped, has a single TRS 1/4" jack on one end and two 1/4" TS jacks on the other end. This end of the cable plugs into the insert jack on the back of the DigiMAX LT. The other ends of the cable plug into the input and output of the outboard unit. If the outboard unit does not work immediately, you may want to try swapping the jacks that are plugged into the input and output of the outboard unit. Insert Jacks As Analog Outputs Example 1 You may have noticed by now that the DigiMAX LT does not have a standard analog output. In the event that you want to have analog outputs as well as the lightpipe output, you can use the inserts as analog outputs. Plug the cable in until you feel 6 OPERATIONS 3 it `click' once. Using the insert in this fashion will not break the signal chain and will allow the lightpipe output to function correctly. Insert Jack As Analog Outputs Example 2 In the event that you do not need the lightpipe output, you can use the inserts as analog outputs. This cable is Y-shaped, has a single TRS 1/4" jack on one end and two 1/4" TS jacks on the other end. This end of the cable plugs into the insert jack above the input on the back of the DigiMAX LT. By using the insert as an analog output with an insert cable, you will not be able to pass a signal through to the adatTM (lightpipe) output. Second, you would hook a BNC cable from the word clock output of the sending device to the word clock input on the back of the DigiMAX LT. Bypassing The DigiMAX LT Preamps The DigiMAX LT can be used as an analog to digital converter. This cable is Y-shaped, has a single TRS 1/4" jack on one end and two 1/4" TS jacks on the other end.
